Lab with a Pu-238 power source. It requires that the Pu-238 source activity is to be 1,111 TBq producing 1 KWe. The physical half-life of Pu-238 is 87.7 years and its primary decay is an alpha emitter with an average energy of decay shown to be 5.495 MeV.

a. How much energy in the form of heat is generated by the Pu-238 if the conversion efficiency is 25%?

b. What activity would be required to meet the requirements of 1 KWe?

c. If the source is Pu-238 oxide (PuO₂), what is the mass of the oxide required?
